Nobody told me Lion won't install when there's a Bootcamp partition. But there is one on my iMac. What now?
iMac, Mac OS X (10.7)
Backup Lion so you can reinstall it. It might come to that.
BackupLion
Installing Lion clean from that fresh and toasty DVD - does that mean I'm gonna toast my 10.6.8 apps and data as well?
Backup your user files and folders manually (drag and drop) fromall partitions/OS's installed to a external powered drive and disconnect this drive, before proceeding with any OS upgrades.
Oh golly. That's one helluva job. Restoring my data from a full 10.6.8 TimeMachine-Backup won't work, I reckon?
is this true ?
its then a no go
Installed perfectly for me with a Bootcamp partition.
Also works for me. Check if your disk uses GPT partitioning or MBR. What actually happens is that the Lion installer tries to resize your Macintosh HD drive in order to add a small (600MB) bootable recovery partition after it.
I have the same problem. Apple's suggestion that I:
1. Wipe out the hard disk including the Boot Camp partition containing Windows 7 with many programs installed;
2. Re-install Snow Leopard;
3. Update Snow Leopard with all software updates;
4. Re-download Lion and install it;
5. Re-install all of my Mac programs - many take a long time to install;
6. Re-update all of my Mac programs;
7. Re-create the Boot Camp partition;
8. Install Windows 7;
9. Update Windows 7;
10. Re-install all of my Windows 7 programs;
11. Re-update all of my Windows 7 programs.
12. Restore my Windows 7 user data.
13. Restore my Mac user data.
IS INSANE!
I'll only do it if Steve Jobs will come over and sit beside me to tell me how much better an App Store install of a major operating system release is better than having a DVD. Steve, I live in San Francisco and am available anytime.
Here's another way. Make sure you use GPT partitioning and check if your disk Macintosh HD is resizable with diskutil resize. If that works, you should have no problem.
In order to migrate your disk from MBR to GPT, it's going to get tricky, but doable. Basically:
1) Boot from your snow leopard dvd
2) Make a backup image of the Macintosh HD to a DMG on an HFS formatted external drive of sufficient capacity
3) Make a backup image of the Bootcamp partition to another DMG on a HFS formatted external drive, again with sufficient capacity
4) Remove all partitions from your internal drive
5) Change the partitioning scheme to GPT
6) Re-add partitions
7) Restore from the DMG images
8) Resize the Macintosh HD to something smaller (say 1GB smaller)
9) Attempt installing again
Two words: teh suck. This is starting to feel *a lot* like Windows nonsense. You know what I'm gonna do? Luckily this very weekend a used but quite recent MacBook Pro will arrive here, destined to be my next productivity machine. It's blank and will hopefully upgrade to Lion with minimum hassle.
Just checked with disk utilities says my HD has a GUID partition scheme
Is this good or bad ?
I have bootcamp.
Regardless of the OS, resizing partitions is tricky.
You don't have to upgrade to Lion from Snow Leopard. Install Lion from scratch via the restore DMG to DVD or USB Stick method.
Thanks d3vil. I thought GPT partitioning was already used on the drive but I'll check tonight when I get home from work. My drive is a 512GB Apple SSD drive on a MacBook Pro Mid 2010. Perhaps that is the complication.
Don't blame Apple for your ignorance...
It's good. Try resizing the Macintosh HD from the terminal using:
-bash-3.05# sudo diskutil resizeVolume / -1G
Nobody told me Lion won't install when there's a Bootcamp partition. What now?
